Allograpta - Allograpta obliqua - female

Allograpta - Allograpta obliqua - Female
Santa Clara County, California, USA
February 12, 2014
Size: 9 or 10mm
on a Meyer lemon leaf

Moved from obliqua or exotica.

Markings on tergite 2 are consistent with obliqua; see:

Moved from Allograpta.


The median longtitudinal marking on tergite 4 can just be seen and the sublateral pale stripe is oblique. A thin, narrowing towards middle, separated pale strip at front edge of tergite 2 and tergite 1 is pale are features not found in Sphaerophoria novaeangliae. This is Allograpta.

Moved from Syrphini.

Moved from Syrphid Flies.

Moved from ID Request.

I don't think this is Platych
I don't think this is Platycheirus - note the yellow-white rather than black face and the complete abdominal bands. My best guess is something in Allograpta, perhaps A. obliqua given the yellow on the katepisternum; it's possible it's something in Sphaerophoria, but the lack of complete banding on the side of the thorax makes me hesitant. In some ways the scutellum resembles that of Toxomerus politus, but the hind margin on the eye is too straight and the thorax should have a complete yellow margin.

Moving to Syrphidae to try and get some more expert opinions on this fly...

(and yes, female - note the wide spacing of the eyes. in some Syrphidae, the males have eyes that don't touch, but the spacing is usually narrower; in the genera I listed above the male eyes touch, if I recall correctly)
